1.0 GENERAL INFORMATION
1.1 Functional Overview
The VCom TRI1819 is an outdoor RF transceiver for use in broadband wireless systems. The TRI1819 combines a
low noise downconverter, high power upconverter, antenna and high rejection duplexer to offer a fully integrated
solution for 1.9 GHz subscriber terminals. The TRI1819 integrated subscriber transceiver serves to frequency
translate and amplify the upstream and downstream signals to the appropriate intermediate frequencies for use by
the indoor DOCSIS modem. The TRI1819 and antenna are situated outdoors and connected to a cable modem
indoors by a low cost 75 ohm cable (i.e. RG-59, RG-6 or similar). A single RF F-connector on the weatherproofed
enclosure provides the interface to the transmit/receive antenna for rapid installation.
1.2 Module Features
• Output Power up to +33 dBm EIRP
• Automatic transmit RF mute when modem is not transmitting
• Low Noise: < 6 dB typical
• Digital temperature compensation to guarantee specifications over full operating temperature range
• All local oscillators are frequency synthesized and locked to a common internal high stability reference
